"destinations often change for outbound Tankers....that is true...but they do depart with some destination given....otherwise which way would the Captain know to point his vessel? Commonsense says the Tankers are headed to consumers....take your pick of any except for Iran which does not need to import much oil right now."
Actually they often leave WITHOUT a final destination - they head for "Europe" or "N America" and their final destination is chosen when the cargo owner decides where he/she can get the best deal. And sometimes if the price falls suddenly they'll park up for a while somewhere (like Falmouth in the UK) until they decide what the best option is.
"You do not know what the various Intelligence Agencies and Militaries know about the May incident or this one....yet you sure want to let on like you are in the know somehow and seem to think we should just accept what you offer."
Lets just remember that believing in the word of the Intelligence community hasn't necessarily been an intelligent thing to do over the last few decades - Indian Intelligence in 1962, Russian intelligence in 1979, the USA in Vietnam, the British in 1982, and the whole Iraqi WOMD saga are all examples of catastrophic misjudgments
